Loads

A spring Wisconsin snowstorm demonstrates how a building design practice may lead to higher risk.

An unusual design project gives this CM international exposure.

Getting information up front on sprinkler systems can ease the design process.

Finding opportunity in the growing solar panel market.

An unusual project with an uncommon shape presented the kind of design challenge truss technicians don’t see every day.
 

A little forethought can prevent the potential overstress that occurs when deflection leads to rooftop ponding.

A best practice for building designers: find a friend to check your load paths.

Lumber Design Values

No matter the species, component manufacturers (CMs) purchase and rely on the accuracy and reliability of many different lumber design properties, including: bending (Fb); shear parallel to grain (Fv), compression perpendicular to grain (Fc^), compression parallel to grain (Fc), tension parallel to grain (Ft), and modulus of elasticity (E and Emin).

Can I put a wood deck (1/2 in. plywood) on top of the bottom chord of a 26 foot span truss 24 inches on center?

We are building churches in Europe. These are modified pole barns and we are trying to use local materials and local volunteer labor. Since the truss is the heart of the building, I am looking for a method to test some completed trusses before the building is started to make sure they are strong enough.
